main files:
COMSOLstudy_trial2.m
->change "runNum" and "Iterations" variables. See comment in the program
->change "filepathmain" and "imgpathmain". See comment in the program
should then be good to go

dependent files:
fgenerateRandomGNDTERMLabel.m
fgenerateRandomCurrent.m
fgenerateRandomSplineCoord.m
fgenerateRandomWidth.m
